DRILL FOR WOOD AND OTHER MATERIALS.

5PECIFICAI'ION forming part of Letters Patent No. 334,757, dated January 26, 1.886.

Application filed May 23, 1865. Serial No. lfi6,489. (No model.)

To all whom it may concern:

Be it known that I, RUDOLPH DHEUREUsE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Drills for Wood and other Materials, of which the following is a specification.

My invention relates to drills for wood or other materials, and it is applicable to apparatus to be operated by hand or any other motive power.

The object of my invention is to so organize a drilling apparatus that it may be used for the purpose of drilling holes in places difficult or impossible of access when the ordinary drilling contrivancessuch as braces, &c. cannot be depended upon for performing the work.

One of the purposes for which my apparatus is especially applicable will be the drilling of holes into the window frames or casings of upper story Windows, when it is desired to provide for temporary or permanent arrangement for cleaning, repairing, or for the application of fire-escape apparatus.

My invention comprises a frame for supporting the drilling mechanism, which frame is provided with adjustable clamping mechanism at its foot; and this frame maybe made in more than one part, thus rendering it capable of being adjusted and fixed so that the drill may move in a direction parallel to the vertical axis of the clamped foot-piece, so as to drill vertically, or adjusted at any desired angle with reference to the object to which the apparatus is clamped, so as tobore holes at any desired angle with relation to said object. The drilling mechanism may be mounted upon this structure in a sliding frame, or the drillspindle may be combined with any one of several wel1known kinds of drill-feed devices. In either organization the construction is such as to insure a progressively-forward movement of the drill of the requisite speed simultaneously with its rotating movement.

The organization of my apparatus is such that it may be operated so as to bore the hole toward the operator, the drill-point moving in the direction of the operator,instead of away from him.

The subject-matter for which I desire protection in this instance is pointed out in the claims at the end of this description.

In the accompanying drawings, which form a part of this description, and in which like letters indicate like parts, Figure l is a side elevation of one form of my apparatus; Fig. 2, a front elevation of the same; Fig. 3, a detached portion showing one form of device for insuring the progressive forward movement of the drill. Fig. 4 is a front elevation of another form of the apparatus; Fig. 5, a side elevation of the same; Fig. 6, aview of one ofthe modes of feeding the drill that may be employed, and Fig. 7 a detail view of a part of Fig. 6.

A represents the drill-frame, with clamps B B, one of which may be permanently affixed to the stanchion d of frame A.

E is the drill-spindle, provided with the drill-chuck O and with gear G, which co-operates with the gear 9, located upon the driving- I may be extended or contracted to suit the work to be performed.

The drill-spindle E in the form of apparatus shown in Figs. 1 and 2 slides through the gear G, which, by a screw-pin runningin the groove h, communicates its rotary motion to the spindle E, as will be understood by reference particularly to Fig. 3.

In Fig. 1 the drillframe A is represented to be attached to the narrow projection of a window-frame, F, to bore through which and the hanging stile S the chuck has to pass close to the outer wall, N, projecting from the windowframe. The hole is shown as already bored and the chuck provided with the countersinkbar P, which is passed through the hole and furnished with the cutter R. In this condition, if the pull M is pushed outward and the drill revolved in the proper direction, the countersink may be furnished to the depth required.

As shown in Figs. 1 and 2, the clamps B B are represented to be adjusted apart by setscrews and a screw, a, within the stanchion d, to secure the clamp to the window-frame or other object.

In operating the form of apparatus shown in Figs. 1 and 2 the revolution of the drivingspindle will give the requisite rotary motion to the drill-spindle, and the gradual drawing forward of the pull M will insure the progressively forward movement of the drill spindle.

The form of apparatus shown in Figs. 4 and 5 is provided with a sliding frame, D, to which the dri1l-spindle is properly secured, and with gears and crank for effecting the revolution of said spindle. Power applied to the crank-- shaft will give revolution to the drill-spindle, while the slide D is fed progressively forward by a cord, belt, or chain, c, operated byawheel or crank, F, nearer the foot of the device than the driving-shaft of the drill-spindle. The manner in which this progressively forward movement of the drill-spindle is accomplished in this embodiment of my invention will be clearly understood without a detailed description thereof.

Figs. 6 and 7 show another method of feed ing the drill which may be employed instead of that shown in Figs 1 and 3. In these views Figs. 6 and 7, J indicates the threaded portion of the drill-spindle E, which meshes into a nut, K, which is held in place by a screw-pin, P. The revolving drill-spindle feeds in the desired direction when the tooth Lis allowed to catch into one of the notches n in the rim of the nut K.

Various other modifications of the drill-feed ing, clamping, or adjusting means may be employed without changing the character of my invention, and the apparatus, though represented in the drawings as applied to boring wood, may be used with. slight modifications for drilling other materials.

I specially design this apparatus for light work, and as a handy tool for such purposes its parts will be made as light as may be consistent with proper strength; but it is not my purpose to restrict the use of this apparatus to any particular work, as its adaptability to heavy work is obvious.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is v 1. 'A'drilling-tool comprising a frame, having a hinged foot constructed to be adjustably secured near the object to be operated upon, mechanism for imparting a progressively forward movement to the drill-point, and mechanism for imparting the requisite rotary motion thereto, substantially as and for the purpose set forth.

2. A drill embodying in its organization a frame whose foot can be adjustably secured near the object to be operated upon,and whose top portion can be adj ustcd to enable the drilling-tool to penetrate at an angle to the vertical axis of the foot of the frame, gearing for imparting rotary motion to the drilling-tool,and drill feed mechanism whereby said tool is progressively fed forward simultaneously with its rotation, substantially as set forth.

3. The frame A, whose foot-piece is provided with a clamping mechanism, one of the jaws, B, whereof is rigidly secured to said footpiece, in combination with a drill-spindle. gearing for imparting rotary motion to said spindle, and the pull M. connected to the top extension of the drill-spindle and extending down near the foot of the drill-frame,whereby a forward or backward movement may be imparted to the drilling-tool, substantially as set forth.-

4. The frame A, constructed to have one of its members adjusted at an angle with relation to its other member, and provided with adj ustable clamps at its foot,in combination with the drill-spind1e,gearing to effect the rotary movement of said spindle,and thepull M,connected to the top extension of said spindle and extending down to near the foot of the drillframe,wherebyaprogressively forward movement of the drill-spindle may be effected,substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 16th day of May, A. D. 1885.

RUDOLPH DHFJUREUSE.
